Abstract
This invention relates to the treatment of fibrous materials such as textiles to make them water-repellent. It has been found that the amount of organopolysiloxane used in treatment baths for those purposes can be considerably reduced by replacing up to 70% by weight of the emulsified organopolysiloxane with 30 to 65% by weight of the replaced organopolysiloxane of an emulsified oxidized polyethylene. Even though oxidized polyethylene does not by itself impart water-repellent properties to textiles its combination with the organopolysiloxane does give treated fabrics with excellent water-repellent properties.
